摘要
The present invention provides an integrated switching regulator device which comprises a switching mode regulator comprising an input voltage source and a switching circuit coupled to the input voltage source to generate a pulsed voltage from the input voltage, and a low pass filter coupled to the switching regulator configured to filter the pulsed voltage to provide a regulated voltage to a load. The low pass filter comprises at least two LC stages, wherein the first LC stage comprises an air cored inductor and each subsequent LC stage comprises a non-air cored inductor. The switching circuit comprises two or more switching elements configurable to operate at a switching frequency of several MHz.
